Let me help you see through my eyes. Given a chance I'd rather have a life partner than adopt or have a child through a surrogate.

Many before me have decided to the path of parenthood. I have nothing against them and surely admire the strength and paternal/maternal instinct to take on this task.

I would often go back to me and my parents. I love them unconditionally and am very thankful of the years of nurture they have showered me. But it comes to a point that, like them, I would want to live my life as my own.
Our culture is quite Asian in this aspect and I am the guy who didn't visit his sick grandmother because I didn't want her to see the pity in my eyes.

I wouldn't want my future child to undergo the stress of looking after me when I am unable to accomplish tasks anymore. I know I will deteriorate and when that time comes I would like to have someone to deteriorate alongside with me.
